teebird long -high speed turn 0 fade 1 technically that would be overstable . im guessing your pro tl is a little beat i would invest in a star tl , i love teebirds but i wouldnt suggest it until you can throw closer to 300.

You've got form issues. Unless you're throwing into a big headwind, most of your drivers should be able to hold stable up to at least 250-300' at 150g weights. If you're flipping drivers at less than 200', you're rolling your wrist or have some other form problem.

Here are a couple of tricks. I read this somewhere when I first started playing and I think it's why I never have had an issue with what people mistakenly refer to as OAT.

key point #1 - Wrist Down - Find the line on your palm that starts close to your wrist and goes at a 45 degree angle towards your first finger. Hold your hand out like you're shaking hands and then swivel your wrist so that the line on your palm lines up with an imaginary line running down the center of your forearm. Now put your disc in your palm right in that line and close your fingers and thumb around it. This is the angle you should keep the disc at when throwing if you want a level nose down throw.

key point #2 - straight pull through - Stand facing a wall with just enough room between your chest and the wall for a disc to pass through. Practice a few reach backs and pull throughs, slowly, this close to the wall as a way to teach what a straight pull through should feel like. When you're on the tee pad, think about a wall being there and remember to pull through straight and close to the body so you won't scrape your hand on the imaginary wall.

That wall thing is new...
150 to 300 in a day WTF did you do?!
Really ...
Vloklgirl, let that follow through really come around, and the wrist down and arm straight thing is great, as is a really straight back-stand quite erect, it opens the hips so they swing with less effort.
hope it helps
TEEbird!

After playing today, slowing down and really paying attention to my pull-through and release and the disc and its flight, I think I figured out what's going on.

In trying to out throw hubby, I'm rushing the pull-through and grip locking, sending everything right. Then, by adding the X-step, the problem is accentuated with the hip pain from the left leg crossing behind causing an added funky upper body twist.

My superlight Monarch still turned a little right, but nothing like before, and it came back just like it should. Oh, and all my throws seemed to come out faster and flatter.
